水在高温高压下能展示迷人的物理性能.在26GPa和4 200K的条件下,稠热水会分解成H和OH,在反应中可传输O并同时还原NO2和氧化CO.通过计算常温常压和稠热状态下各反应的热力学参数,结果表明,在常温常压下氧化、还原循环过程标准吉布斯自由能变ΔG总分别为343.806和318.976kJ·mol-1,反应不能自发进行;在稠热状态下氧化、还原循环过程吉布斯自由能变ΔG总分别为-551.945和-1 027.412kJ·mol-1,速控步的活化能分别为73.282和161.054kJ·mol-1,反应可以进行.
Under the conditions of high temperature and high pressure, the water can exhibit attractive physical properties. Under 26GPa and 4 200K conditions, the hot water decomposes into H and OH, which can transport O and simultaneously reduce NO2 and oxidize CO. By calculating the normal temperature and pressure The results showed that the standard Gibbs free energy ΔG changes are 343.806 and 318.976 kJ · mol-1, respectively, at normal temperature and pressure. The reaction can not proceed spontaneously. At In the hot state, the Gibbs free energy changes ΔG in the oxidation and reduction cycles are -551.945 and -1 027.412kJ · mol-1, respectively. The activation energies of the quick step are 73.282 and 161.054kJ · mol-1 respectively. get on.
